Stephen Gray –
The Rainbow Shark is a visually striking fish with vibrant red fins. I kept it in a 55-gallon tank with larger, calm fish. It stayed peaceful as long as it was alone. I feed it a mix of flakes and bloodworms daily. It’s active but not overly aggressive toward other species.
Jason Sutherland –
It looks beautiful in the tank, but I noticed it became territorial after a few weeks. I had to remove a smaller fish that was too similar in size. Feeding is easy with a variety of foods.
Bella Wilkins –
Great color and active behavior. I keep it alone in a spacious tank with plenty of plants and rocks. It doesn’t eat much but stays healthy with regular flake and vegetable meals.
